At the conclusion of fifteen miles we entered a dense forest of gum trees and brushwood which we penetrated with difficulty; after walking nearly five miles through it, we came to a tea tree and samphire swamp, the water of which was brackish; at the eastern extremity of it, we reached the base of two remarkable isolated hills, for which we had been steering; we found each of them to be composed of one mass of granite; they appeared to be detached from some high land stretching away to the southward; we gave the northern one the name of Mount Caroline, and the southern was called Mount Stirling, after my fellow traveller, Mr. W.
